My Brother has a 2004 RS6 saloon. Had it about 3 months and is experiencing hesitation and stuttering. Been on diagnostics which showed MAF sensor fault. Replaced both internal units with genuine Audi parts. But its no better and nothing else on diagnostics. Car has had new cambelt , plugs etc very recently.
Any advice greatly appreciated.
Thanks
Neil
Stuttering and hesitation.
RE: Stuttering and hesitation.
I'm sure there is another component to the MAF set up, sadly I'm damned if I can remember what it's called -

RE: Stuttering and hesitation.
sounds like tired coilpacks
I would scan again and see if there are any misfires. £30 each from Audi x 8

Hi there and sorry to hear that, where did he get his fuel from, could be dodgy fuel.
RE: Stuttering and hesitation.
What was done on the service? What plugs were fitted?
Can you post some logs? what are the idle g/s numbers on the Mafs?

The car was serviced by Camberley Audi in July and had a cambelt and major service including plugs etc. Not sure what type. Car is going back on diagnostics this afternoon. Let you know what happens.

RE: Stuttering and hesitation.
RS6 don't really suffer from coilpack problems.
Look at the MAFs again, make sure they are seated properly. I'm betting on this. The electrical connectors deteriorate, too. What was the daignostics error code?
Have you got access to a vagcom? Or even a generic ODB2 scanner that can show live engine data?
Could also be a vac leak. When you've got the air filter housing off to check the MAF seating, check all the little vac hoses (and also the master cylinder one.

Re: RE: Stuttering and hesitation.
I've had two replaced, one on each bank. That was the cause of my O2 sensors going bad. At least that's what they told me.Shoppinit wrote:RS6 don't really suffer from coilpack problems.
I suspect my O2 failures had more to do with the oil being over filled.
RE: Re: RE: Stuttering and hesitation.
Yeah, the S4 B6 and S6 have terrible problems with the coil packs. The RS6 by comparison has very few problems with them. No more than the usual background noise.

Does it do it under light throttle or when under load (ie low revs, high gear up a hill)
